Description

Technical Field

[0001] The utility model belongs to the technical field of mold processing, in particular to a sleeve type hot forming positioning lifter. Background Art

[0002] The trimming and punching of hot-formed parts is not like traditional stamping, where the final parts can be obtained through trimming and punching dies, because its tensile strength has reached about 1500MPA, and the area of ​​the product that needs laser cutting, in order to ensure the accuracy of laser cutting, positioning is required to ensure its stability. Locating pins are set in the waste area of ​​the product, and straight-edge shapes are turned out for laser cutting positioning, which is the main means now. Straight-edge shapes will have the problem of locking the locating pins, and the installation depth of the locating pins is different. Therefore, a lifting device needs to be set nearby to help the parts detach from the locating pins. After the locating pins are ejected, the subsequent robot clamps the locating pins.

[0003] The existing hole-turning positioning jacking device has a lifting head that is difficult to adjust in height during the lifting process and is not convenient for ejecting positioning pins installed at different depths on the mold surface. In addition, the lifting head is difficult to disassemble and repair after being used for a long time. Utility Model Content
